Q11 / 196 · NTA Abhyas (NEET) 2020 · Chemistry · Chemical Kinetics

Which of the following statements about zero order reaction is not true

A
Its unit is ${molL}^{- 1} {time}^{- 1}$
B
The graph between log (reactant) versus rate of reaction is a straight line
Correct answer
C
The half life for zero order reaction is independent of initial concentration.
D
Rate of reaction is independent of concentration of reactants

Solution

The unit for zero order reaction is

{molL}^{- 1} {time}^{- 1}

and the half life of zero order reaction is given by

t_{1 / 2} = [A]_{\circ} / 2 k

, where

[A] {}_{\circ}

is initial concentration of reactant.

Hence, the correct answer is option: 'C'.
